From: Rabbi Moshe Sofer
To: Rabbi Simcha Noson Ellenberg
A man whose circumcision accident resulted in the natural urethral opening sealing and a new opening forming is analyzed for the status of petzua daka. The Chasam Sofer finds two potential grounds for leniency — the Teshuvos HaRosh's view that a sealed passage may retroactively indicate the injury was never true petzua daka, and the subject's abundant hair growth — but declines to permit the marriage on his own authority and defers to other distinguished rabbis for a final ruling.
